Performance analysis of model predictive control for voltage source inverter

While the classical control techniques for three-phase two-level three-leg inverters are based on pulse width modulation or 3-D space vector modulation, this paper presents a Finite Control Set Model Predictive Control (FCS-MPC) strategy for a two-level three-leg voltage source inverter with resistive-inductive load. Model predictive control method chooses a switching state that minimizes the error between the output currents and their references. Firstly the performance of the proposed predictive control method is compared with pulse width modulation control. Secondly the performance of controller is analyzed with various conditions is carried out. The proposed controller offers excellent reference tracking with less current harmonic distortion for all conditions. The proposed system´s performance is investigated using a MATLAB simulation model.
